Introduction
Once your gamma is created, there are a few ways to add to it: edit directly on your cards, ask the agent to make changes for you, or add images and other media. This guide walks you through each one.
🌀 Insight: You never have to use AI for everything. Anything the agent creates, you can change by hand, and anything you change by hand stays put when you ask the agent for more.
Looking to create a brand-new gamma instead? Start from the prompt bar on your dashboard, and the agent builds it for you.
Option 1: Edit Directly on Your Cards
Make sure the toggle at the top-left of the editor is set to the pencil (editing mode), not Agent.
Click into any card and start typing to add or change text.
Move, resize, and rewrite anything by hand.
To add new content, click Add block in the toolbar at the top of the editor, or type / inside a text block.
Option 2: Ask the Agent
Open the agent chat on the left side of the editor. Click Show chat if it's hidden.
Describe what you want in your own words, for example "Add a slide comparing our three pricing tiers."
The agent makes the change and tells you which slides it touched. Your other slides and any edits you've made by hand stay as they are.
To change just one slide, click Edit with Agent on the left edge of that slide and type what you want changed.
🔷 Note: In gammas made before Gamma 5, click Agent at the top right to edit all slides, or Edit with Agent at the top-left of a slide.
Option 3: Add Images and Media
Images: Click Add block, select Images, then choose Image upload or URL. You can also pick from AI images, stock photos, GIFs, icons, and more.
More than one image: Cards can hold more than one image. Add another the same way, or ask the agent something like "Put these two images side by side."
Video: Embed a video from YouTube, Vimeo, Loom, Wistia, or TikTok using its link.
Audio: Embed audio from a link, for example with the Spotify block or Video or audio embed.
Option 4: Add a Graphic from Imagine
Need a standalone visual like an infographic, diagram, or poster? Create it in Imagine, then add it to any gamma as an image.
FAQs & Common Issues
Can I edit by hand, or do I have to use AI?
You can edit anything by hand. Switch the toggle at the top-left to the pencil, then click into any card.
The agent is optional, and your manual edits stay put when you ask it for changes.
How do I undo a change?
Press Cmd + Z (Mac) or Ctrl + Z (Windows).
Each agent request is applied as a single edit, so one undo reverses the whole change.
Undoing an AI change doesn't return the credits it used.
Why can't I type inside a card?
Check that the toggle at the top-left is set to the pencil, not Agent.
If the text toolbar still doesn't appear, refresh the page.
Can I upload a video or audio file from my computer?
No. Gamma doesn't host uploaded video or audio files.
Upload your file to a supported site first, then embed it using the link.
In the Gamma mobile app, you can add a video straight from your camera roll.
How do I change fonts, colors, or a slide's background?
For fonts and colors across your whole gamma, click Styles at the top of the editor.
For one slide's background, click the slide to select it, then use Card background color or Background image in the toolbar.
How do I make a specific formatting change, like deleting a table row or numbering a list?
Ask the agent in plain words, for example "Delete the last row of the table on slide 3."
Or click into the content and use the toolbar that appears.
Can I use my own images when creating a gamma?
Yes. In the prompt bar, click + and select Upload files, then add your images before you generate.
